Description
Technical field
The present invention relates to a kind of regenerating unit that is used for removing the freon that reclaims the impurity such as oil content that freon comprised.
Background technology
Because the freon that is disposed in the atmosphere is the main cause of depletion of the ozone layer and global warming; So reclaim the freon that uses and carry out resolution process; Perhaps after the freon after reclaiming is removed the processing of impurity such as refrigerator oil and moisture, utilize again.
In patent documentation 1, disclose a kind of freon regenerating unit; It disposes hot-water heating system, oil eliminator, compressor, cooler, regeneration freon gas bomb (bombe), Filter dryer midway in the process segment; Thereby will reclaim freon and be refined into regeneration freon; Wherein, said hot-water heating system is used for heating being filled with the recovery freon gas bomb that reclaims freon, and said oil eliminator is used for the oil content that freon contained after the gasification is separated; Said compressor is used to compress the freon with after the oil content separation; Said cooler makes freon cooling and the liquefaction after the compression, and said regeneration freon gas bomb is used to fill the freon after the liquefaction, and said Filter dryer is used for removing the moisture that freon contains.
By the way; Because the freon boiling point is low; Comparing and reclaiming the impurity that contains in the freon is that oil content and moisture gasify more earlier, thus only just can remove most oil content and moisture through gasification, but can not remove the mist of oil and the moisture of the trace that is contained in the freon after the gasification.
In the simple and easy regenerating unit as above-mentioned freon regenerating unit; The oil content of removing in the freon to be contained through oil eliminator; Remove moisture through Filter dryer, still, owing to can not remove oil content and moisture fully through 1 time processing; So implement twice identical processing, thereby have elongated shortcoming of recovery time.In addition,, regenerating unit is maximized, thereby need the spacious space that is provided with because of the existence of oil eliminator, cooler and Filter dryer etc.
In view of such present situation, the applicant develops and has proposed the freon regenerating unit of the new mode of utilizing electric dust collecting means shown in the patent documentation 2.This freon regenerating unit is following structure: through making recovery freon after the gasification that comprises oil content impurity such as (mist of oils) through being wound up as in the spiral helicine TFE tubulation (tube); Thereby utilize rubbing action to make impurity charged; Remove through making on the collecting electrode of this charged impurity attached to electric dust collecting means then, thus regeneration freon.After this, according to discovering of the application inventor, if the carried charge of the impurity in the freon increases; Then the processing of removing of impurity becomes easier; And on collecting electrode, apply the voltage of about 2kv, but, then can improve security if can use the voltage lower than this voltage.Therefore, the new device after reference point is improved is adopted in proposition.
